DESCRIPTION OF THE RELATED TECHNOLOGY

A wireless local area network (WLAN) may be formed by one or more accesspoints (APs) that provide a shared wireless communication medium for useby a number of client devices also referred to as stations (STAs). Thebasic building block of a WLAN conforming to the 802.11 family ofstandards is a Basic Service Set (BSS), which is managed by an AP. EachBSS is identified by a service set identifier (SSID) that is advertisedby the AP. An AP periodically broadcasts beacon frames to enable anySTAs within wireless range of the AP to establish or maintain acommunication link with the WLAN. In a typical WLAN, each STA may beassociated with only one AP at a time. To identify an AP with which toassociate, a STA is configured to perform scans on the wireless channelsof each of one or more frequency bands (for example, the 2.4 GHz band orthe 5 GHz band). As a result of the increasing ubiquity of wirelessnetworks, a STA may have the opportunity to select one of many WLANswithin range of the STA or select among multiple APs that together forman extremely BSS. After association with an AP, a STA also may beconfigured to periodically scan its surroundings to find a more suitableAP with which to associate. For example, a STA that is moving relativeto its associated AP may perform a “roaming” scan to find an AP havingmore desirable network characteristics such as a greater received signalstrength indicator (RSSI).

Wireless communication systems are widely deployed to provide varioustypes of communication content such as voice, video, packet data,messaging, broadcast, and so on. These systems may be multiple-accesssystems capable of supporting communication with multiple users bysharing the available system resources (for example, time, frequency,and space). The AP may be coupled to a network, such as the Internet,and may enable a station to communicate via the network includingcommunicating with other devices coupled to the AP.

Some wireless devices in a WLAN (such as, APs or STAs) may be configuredfor extremely high throughput (EHT) operations and supportedfunctionality on a dynamic channel bandwidth spectrum. The dynamicchannel bandwidth spectrum may be a portion of spectrum that includesfrequency bands traditionally used by Wi-Fi technology, such as the 5GHz band, the 2.4 GHz band, the 60 GHz band, the 3.6 GHz band, and the900 MHz band. The spectrum may also include other frequency bands (suchas the 6 GHz band). The wireless connection between an AP and STA may bereferred to as a channel or link. Each band (for example, the 5 GHzband) may contain multiple channels (for example, each spanning 20 MHzin frequency, 40 MHz in frequency, or 80 MHz in frequency), each ofwhich may be usable by an AP or STA. Based on the functionalitysupported by EHT modes of operation, flexibility and extensions toexisting fields, frames and structuring, signaling, and featuresassociated with operability in utilizing wireless resources may bedesired.

SUMMARY

The operating bandwidth may be contiguous or span one or moredisparate sub-channel sets. In some examples, described techniques mayprovide flexible enhancements to reporting mechanisms or subfieldindications signaled by an AP or STA, for increased granularity forchannel bitmap or operating bandwidth indication. In other examples,described techniques may provide flexible enhancements to reportingmechanisms or carrier signaling procedures by an STA, for increasedgranularity for medium sensing or signal quality indication on anoperating bandwidth.

DETAILED DESCRIPTION

The following description is directed to implementations for thepurposes of describing innovative aspects of this disclosure. However, aperson having ordinary skill in the art will readily recognize that theteachings herein can be applied in a multitude of different ways. Thedescribed implementations can be implemented in any device, system ornetwork that is capable of transmitting and receiving radio frequency(RF) signals according to any of the IEEE 802.11 standards, or theBluetooth® standards. The described implementations also can beimplemented in any device, system or network that is capable oftransmitting and receiving RF signals according to any of the followingtechnologies or techniques: code division multiple access (CDMA),frequency division multiple access (FDMA), orthogonal frequency divisionmultiple access (OFDMA), time division multiple access (TDMA), GlobalSystem for Mobile communications (GSM), GSM/General Packet Radio Service(GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio(TETRA), Wideband-CDMA (W-CDMA), Evolution Data Optimized (EV-DO),1×EV-DO, EV-DO Rev A, EV-DO Rev B, High Speed Packet Access (HSPA), HighSpeed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access(HSUPA), Evolved High Speed Packet Access (HSPA+), Long Term Evolution(LTE), AMPS, or other known signals that are used to communicate withina wireless, cellular or internet of things (IOT) network, such as asystem utilizing 3G, 4G or 5G, or further implementations thereof,technology.

In some wireless communications systems, extremely high throughput (EHT)environments may provide additional capabilities over other environments(for example, high efficiency (HE) environments). EHT environments maybe configured to support flexible operating bandwidth enhancements ataccess points (APs) or stations (STAs), such as a broadened operatingbandwidth relative to legacy device operation or granular operationwithin primary or secondary channel bandwidth spectrum. For example, anEHT environment may be configured to allow communications spanning atotal operating channel bandwidth of 320 MHz. The operating bandwidthmay also accommodate concurrent operation on other frequency bands (suchas the 6 GHz band) and a portion of spectrum that includes frequencybands traditionally used by Wi-Fi technology, such as the 5 GHz band,the 2.4 GHz band, the 60 GHz band, the 3.6 GHz band, and the 900 MHzband. The operating bandwidth may be contiguous or span one or moredisparate sub-channel sets. In some examples, operability enhancementsassociated with EHT environments, in particular operation at anincreased bandwidth such as a total operating bandwidth of 320 MHz or160+160 MHz, may make existing (legacy) rules, structures, and signalinginadequate. Additionally or alternatively, operability enhancementsassociated with EHT functionality and an extended supported bandwidthspectrum may leave granular refinements to carrier sensing and signalreporting mechanisms to be desired.

Techniques that extend existing techniques to enhance flexibility and tosupport functionality for EHT environments are described. Extensions mayinclude modifications to existing rules, structures, or signalingimplemented for legacy systems, for example supporting 20 MHz, 40 MHz,80 MHz, 80+80 MHz, or 160 MHz operating modes, to support EHTenvironments (such as 160+160 MHz or 320 MHz operating modes).Extensions may include modifications to existing rules, structures, orsignaling implemented for legacy systems, to support a broadenedoperating bandwidth, including EHT environments, or granular operationwithin a primary or secondary channel bandwidth spectrum. The extensionsmay be enabled by default as part of EHT functionality or indicated bymode, bit combinations, or active fields notifying support for an activemode.

An AP (or STA) may be configured to communicate to a STA (or an AP,respectively) an indication of an extension to existing fields, frames,or features. Such extensions may be indicated in part by themodification of fields or subfields of legacy frames, fields, orreports, and provide for broadened operating bandwidth or less granularoperation within primary or secondary channel bandwidth spectrum. Theextensions may be enabled by default as part of EHT functionality orexplicitly or implicitly indicated by a combination of an operating modeand one or more bits of an active field (for example, by a bit valuewithin the active field). Enablement of the extensions may be based onone or more of capabilities (for example, a reported bandwidth) at theAP or STA, the operating bandwidth of the BSS, or a request forreporting information.

In some examples, an STA may identify an operating mode for a supportedoperating bandwidth. Based on the operating mode, the STA may set thecontrol ID subfield of a control subfield to a value indicative of a BQRindication within the associated control information subfield. The BQRindication may include an available channel bitmap for indication ofwhich sub-channels of the operating bandwidth are available at the STA.Each bit in the channel bitmap may correspond to a particularsub-channel (for example, a 20 MHz channel) within the operatingbandwidth width of the BSS with which the STA is associated. In someexamples, an STA may set the control ID subfield of a control subfieldto a value indicative of an operating mode (OM) control of the STA,within the associated control information subfield. The OM controlindication may be formatted to include one or more subfields, includinga channel width subfield indicating an operating bandwidth widthsupported by the STA for both transmission and reception.

In some examples, an STA may be configured for negotiating schedulingoperability with an AP according to a target wake time (TWT). The TWTfunctionality may define a specific time or set of times for the STA toaccess and communicate on the BSS. The STA may negotiate enablement offrame exchange on a non-primary sub-channel (for example, a secondarysub-channel) to maximize TWT operability at the STA. As part of theindividual TWT negotiation, the STA may format a TWT element. The TWTelement may include one or more subfields, including a TWT parameterinformation subfield of variable length. The TWT parameter informationsubfield may be formatted to include one or more subfields, including aTWT channel subfield. The TWT channel subfield may include an availablechannel bitmap for indication of which sub-channels of the operatingbandwidth are permitted by the STA for enabling frame exchange with theAP.

Additionally or alternatively, EHT devices operating on flexiblebandwidth may support implementation of new structures for one or moreof the described reporting mechanisms or subfield indications. In someexamples, HE-capable APs or STAs may define new variants of a BQRmechanism to support added flexibility and granularity based on anactive operating mode. In some examples, the active operating mode maybe a device mode associated with a specific time during which oroperating bandwidth in which the EHT device may be active to access andcommunicate with an AP or STA. In some examples, the EHT APs or STAs maydefine new variants of an OM control subfield to support addedflexibility and granularity based on the active operating mode. In someexamples, the EHT APs or STAs may define new variants of a TWT parameterset to support added flexibility and granularity based on the activeoperating mode.

In other examples, an STA supporting EHT functionality may supportextensions to checking a network allocation vector (NAV) that representsa duration remaining on a shared channel that is occupied by anotherSTA. Due to extensions and supported functionality for extendedoperating bandwidth spectrum, an STA may perform a NAV checkingprocedure for each of one or more sub-channels in addition to, or as analternative to, the primary channel of the operating bandwidth (that is,the STA may perform a per-channel NAV check). The per-channel NAV checkmay enhance functional granularity at the STA for avoiding signalinginterference with neighboring devices, particularly for operations onsecondary channels distant from the primary channel of the BSS. Inaddition, the system may be configured to include more than one primarychannel based on the extended operating bandwidth. The one or moreprimary channels may be configured flexibly, providing for concurrentoperations of one or more channels (which may be or include one or moreprimary channels) on traditional Wi-Fi frequency bands (for example,such as the 5 GHz band, the 2.4 GHz band, the 60 GHz band, the 3.6 GHzband, the 900 MHz band), and concurrent operation on one or more othershared channels (for example, 6 GHz bandwidth spectrum) spanned by theoperating bandwidth.

Particular implementations of the subject matter described in thisdisclosure can be implemented to realize one or more of the followingpotential advantages. For example, the described extensions of legacystructures may allow for EHT operation of EHT-compatible STAs. Forexample, EHT STAs may coexist with non-EHT STAs that may operate usinglegacy structures. The described extensions may include minimal orrelatively small modifications to existing signaling structures, andallow the harmonious operation of both EHT STAs and non-EHT STAs withinthe same network or BSS. In other examples, the described extensions forNAV checking and the flexible use of channels in different bandwidthspectrum may allow for higher throughput, increased bandwidth and thedynamic adjustment of the channels used for communications between EHTSTAs and APs. In addition, the extensions may allow for non-EHToperation of such STAs when channel conditions (for example, noise,interference) limit the availability for the EHT operating bandwidth.

FIG. 1 shows a block diagram of an example wireless communication system100 that supports a 320 MHz operating bandwidth in accordance withaspects of the present disclosure. According to some aspects, thewireless communication system 100 can be an example of a wireless localarea network (WLAN) (and will hereinafter be referred to as WLAN 100).For example, the WLAN 100 can be a network implementing at least one ofthe IEEE 802.11 family of standards. The WLAN 100 may include numerouswireless devices such as an access point (AP) 105 and multipleassociated stations (STAs) 115. Each of the STAs 115 also may bereferred to as a mobile station (MS), a mobile device, a mobile handset,a wireless handset, an access terminal (AT), a user equipment (UE), asubscriber station (SS), or a subscriber unit, among otherpossibilities. The STAs 115 may represent various devices such as mobilephones, personal digital assistant (PDAs), other handheld devices,netbooks, notebook computers, tablet computers, laptops, display devices(for example, TVs, computer monitors, navigation systems, among others),printers, key fobs (for example, for passive keyless entry and start(PKES) systems), among other possibilities.

Each of the STAs 115 may associate and communicate with the AP 105 via acommunication link 110. The various STAs 115 in the network are able tocommunicate with one another through the AP 105. A single AP 105 and anassociated set of STAs 115 may be referred to as a basic service set(BSS). FIG. 1 additionally shows an example coverage area 120 of the AP105, which may represent a basic service area (BSA) of the WLAN 100.While only one AP 105 is shown, the WLAN 100 can include multiple APs105. An extremely service set (ESS) may include a set of connected BSSs.An extremely network station associated with the WLAN 100 may be coupledwith a wired or wireless distribution system that may allow multiple APs105 to be connected in such an ESS. As such, a STA 115 can be covered bymore than one AP 105 and can associate with different APs 105 atdifferent times for different transmissions.

STAs 115 may function and communicate (via the respective communicationlinks 110) according to the IEEE 802.11 family of standards andamendments including, but not limited to, 802.11a, 802.11b, 802.11g,802.11n, 802.11ac, 802.11ad, 802.11ah, 802.11ay, 802.11ax, 802.11az,802.11ba, and 802.11be. These standards define the WLAN radio andbaseband protocols for the physical (PHY) layer and medium accesscontrol (MAC) layer. The wireless devices in the WLAN 100 maycommunicate over an unlicensed spectrum, which may be a portion ofspectrum that includes frequency bands traditionally used by Wi-Fitechnology, such as the 2.4 GHz band, the 5 GHz band, the 60 GHz band,the 3.6 GHz band, and the 900 MHz band. The unlicensed spectrum may alsoinclude other frequency bands, such as the emerging 6 GHz band. Thewireless devices in the WLAN 100 also can be configured to communicateover other frequency bands such as shared licensed frequency bands, inwhich multiple operators may have a license to operate in the same oroverlapping frequency band or bands.

In some examples, STAs 115 may form networks without APs 105 or otherequipment other than the STAs 115 themselves. One example of such anetwork is an ad hoc network (or wireless ad hoc network). Ad hocnetworks may alternatively be referred to as mesh networks orpeer-to-peer (P2P) connections. In some examples, ad hoc networks may beimplemented within a larger wireless network such as the WLAN 100. Insuch implementations, while the STAs 115 may be capable of communicatingwith each other through the AP 105 using communication links 110, STAs115 also can communicate directly with each other via direct wirelesscommunication links 125. Additionally, two STAs 115 may communicate viaa direct communication link 125 regardless of whether both STAs 115 areassociated with and served by the same AP 105. In such an ad hoc system,one or more of the STAs 115 may assume the role filled by the AP 105 ina BSS. Such a STA 115 may be referred to as a group owner (GO) and maycoordinate transmissions within the ad hoc network. Examples of directwireless communication links 125 include Wi-Fi Direct connections,connections established by using a Wi-Fi Tunneled Direct Link Setup(TDLS) link, and other peer-to-peer (P2P) group connections.

Some types of STAs 115 may provide for automated communication.Automated wireless devices may include those implementinginternet-of-things (IoT) communication, Machine-to-Machine (M2M)communication, or machine type communication (MTC). IoT, M2M or MTC mayrefer to data communication technologies that allow devices tocommunicate without human intervention. For example, IoT, M2M or MTC mayrefer to communications from STAs 115 that integrate sensors or metersto measure or capture information and relay that information to acentral server or application program that can make use of theinformation or present the information to humans interacting with theprogram or application.

Some of STAs 115 may be MTC devices, such as MTC devices designed tocollect information or enable automated behavior of machines. Examplesof applications for MTC devices include smart metering, inventorymonitoring, water level monitoring, equipment monitoring, healthcaremonitoring, wildlife monitoring, weather and geological eventmonitoring, fleet management and tracking, remote security sensing,physical access control, and transaction-based business charging. An MTCdevice may operate using half-duplex (one-way) communications at areduced peak rate. MTC devices may also be configured to enter a powersaving “deep sleep” mode when not engaging in active communications.

WLAN 100 may support beamformed transmissions. As an example, AP 105 mayuse multiple antennas or antenna arrays to conduct beamformingoperations for directional communications with a STA 115. Beamforming(which may also be referred to as spatial filtering or directionaltransmission) is a signal processing technique that may be used at atransmitter (for example, AP 105) to shape and/or steer an overallantenna beam in the direction of a target receiver (for example, a STA115). Beamforming may be achieved by combining elements in an antennaarray in such a way that transmitted signals at particular anglesexperience constructive interference while others experience destructiveinterference. In some examples, the ways in which the elements of theantenna array are combined at the transmitter may depend on channelstate information (CSI) associated with the channels over which the AP105 may communicate with the STA 115. That is, based on this CSI, the AP105 may appropriately weight the transmissions from each antenna (forexample, or antenna port) such that the desired beamforming effects areachieved. In some examples, these weights may be determined beforebeamforming can be employed. For example, the transmitter (for example,the AP 105) may transmit one or more sounding packets to the receiver inorder to determine CSI.

WLAN 100 may further support multiple-input, multiple-output (MIMO)wireless systems. Such systems may use a transmission scheme between atransmitter (for example, AP 105) and a receiver (for example, a STA115), in which both transmitter and receiver are equipped with multipleantennas. For example, AP 105 may have an antenna array with a number ofrows and columns of antenna ports that the AP 105 may use forbeamforming in its communication with a STA 115. Signals may betransmitted multiple times in different directions (for example, eachtransmission may be beamformed differently). The receiver (for example,STA 115) may try multiple beams (for example, antenna subarrays) whilereceiving the signals.

WLAN PDUs may be transmitted over a radio frequency spectrum band, whichin some examples may include multiple sub-bands or frequency channels.In some examples, the radio frequency spectrum band may have a bandwidthof 80 MHz, and each of the sub-bands or channels may have a bandwidth of20 MHz.

For example, the STA 300 may bean example of aspects of the STA 115 described in FIG. 1. The STA 300can be configured to send and receive WLAN frames (also referred toherein as transmissions or communications) conforming to an IEEE 802.11standard (such as the 802.11ac, 802.11ax, or 802.11be amendments to the802.11 family of standards), as well as to encode and decode suchframes.

The memory 320 also can storeprocessor- or computer-executable software code 325 containinginstructions that, when executed, cause the processor 310 to performvarious functions described herein for wireless communication, includingreception of a downlink frame and generation and transmission of anuplink frame.

The processor 310 includes an intelligent hardware device such as, forexample, a CPU, a microcontroller, an ASIC or a PLD such as an FPGA,among other possibilities.

The transceiver 330 can communicatebi-directionally, via the antenna 340, with at least one AP 105 as, forexample, shown in FIG. 1. Although only one transceiver 330 and oneantenna 340 are shown in FIG. 3, the STA 300 can include two or moreantennas. For example, in some STA implementations, the STA 300 caninclude multiple transmit antennas (each with a corresponding transmitchain) and multiple receive antennas (each with a corresponding receivechain).

FIG. 4A shows an example of a control element format 400-a that supportsa 320 MHz operating bandwidth in accordance with aspects of the presentdisclosure. Control element format 400-a may be usable forcommunications between a STA and an AP. For example, the control elementformat 400-a may be implemented by an STA supporting EHT functionality,for extensions to reporting indications associated with one or morecontrol subfield formats of a control field form. The control field formmay vary in subfield values or in subfield formatting based on supportedfunctionality at the STA, known as a control field variant. The controlfield may contain a sequence of one or more control subfields (forexample, as part of an A-Control subfield) in which each controlsubfield contains a control identification (ID) subfield and controlinformation subfield, in accordance with the IEEE 802.11ax or 802.11beamendments to the 802.11 set of standards.

The STA may identify an operating mode for a supported operatingbandwidth. Based on the identified operating mode, the STA may determinea value for one or more parameters of a BQR for transmission to anassociated AP. For example, the STA may set the control ID subfield of acontrol subfield within control element format 400-a to a valueindicative of a BQR indication within the associated control informationsubfield. The BQR indication may indicate one or more sub-channels ofthe operating bandwidth available at the STA. For example, the BQRindication within the control information subfield may include anavailable channel bitmap spanning 8 bits, for indication of whichsub-channels of the operating bandwidth are available at the STA. Eachbit in the channel bitmap may correspond to a particular sub-channelwithin the operating bandwidth width of the BSS with which the STA isassociated. In addition, the BQR indication within the controlinformation subfield may include a reserved subfield, spanning 4 bits.

In addition, each bit field of the available channel bitmap may indicatea channel availability for each of the one or more sub-channels. In someexamples, the indication may further include a duration of time that theone or more sub-channels are available or occupied by data traffic. Forexample, the available channel bitmap may support binary indicationrepresentative of channel availability for the associated sub-channel ofthe operating bandwidth. Based on current specification, in accordancewith the IEEE 802.11ax or 802.11be amendments to the 802.11 set ofstandards, a bit field may be set to 0 to indicate signal presence (alsoknown as busy) and set to 1 to indicate idleness on the associatedsub-channel. Extensions to the supporting functionality, as part ofadded flexibility for EHT operability enhancements, may allow reversalof the current meaning for each bit field of the channel bitmap. Forexample, a bit field value of 0 may indicate idleness on the associatedsub-channel and a bit field value of 1 may indicate signal presence onthe associated sub-channel.

Based on the supported EHT functionality, the STA may supportflexibility extensions within the available channel bitmap, to indicategranularity associated with the mode of operation. The flexibilityextensions may promote scaling of represented sub-channel features (forexample, bandwidth granularity) associated with the bit field values ofthe channel bitmap. The flexibility extensions may be enabled by the STAbased on default operations associated with the EHT functionality or oneor more mode, bit combinations, or active fields indicating the activemode is supported, including one or more bit indications within a BQRfield or EHT operation elements of the control element format 400-a.

In some examples, the STA may dynamically alter the sub-channelassociation for each bit within the channel bitmap based on theoperating bandwidth specified in a BQR poll (BQRP). In some examples,the STA may dynamically alter the granularity of the available channelbitmap based on the supported operating bandwidth of the BSS. That is,the STA may alter the granularity of the channel bitmap according to theAP operation of the BSS supporting the communication link. In someexamples, the STA may dynamically alter the granularity of the availablechannel bitmap based on the supported capability (for example, reportedbandwidth) at the STA or based on the supported capability (for example,reported bandwidth) at the AP.

The alterations may be such that each bit field within the channelbitmap 400-b for the control information subfield is representative ofan equal allocation of the supported operating bandwidth, as shown inFIG. 4B. That is, the bandwidth unit indicated within each respectivebit of the channel bitmap may be obtained according to the quotient ofthe total operating bandwidth allocation (such as 320 MHz) divided bythe size of the bitmap (for example, number of bits). For example, foran EHT supported operating bandwidth allocation of 320 MHz, each bitfield of the 8 bit channel bitmap may represent a sub-channel allocationof 40 MHz, respectively. In other examples, for an EHT supportedoperating bandwidth allocation of 80 MHz, each bit field of the 8 bitchannel bitmap may represent a sub-channel allocation of 10 MHz,respectively.

Alternatively, as shown in FIG. 4C, the alterations to the sub-channelassociation may be such that each bit field bitmap within the channelbitmap 400-c for the control information subfield may correspond to ascaled distribution pattern. That is, each bit field within the channelbitmap may correspond to sub-channels of different bandwidths. Forexample, for an EHT supported operating bandwidth allocation of 320 MHz,one or more bit fields of the 8 bit channel bitmap may represent asub-channel allocation of 40 MHz, and one or more alternative bit fieldsmay represent a sub-channel allocation of 60 MHz, 80 MHz, or any othersub-channel allocation within the operating bandwidth. In otherexamples, for an EHT supported operating bandwidth allocation 80 MHz,one or more bit fields of the 8 bit channel bitmap may represent asub-channel allocation of 10 MHz, and one or more alternative bit fieldsmay represent a sub-channel allocation of 20 MHz, 30 MHz, or any othersub-channel allocation within the operating bandwidth.

Based on the one or more parameters of the BQR indication, including thesupported bit field value indication, the STA may transmit theconfigured BQR to an associated AP. The one or more parameters mayindicate availability within each of the sub-channel partitions (forexample, 8) of the operating bandwidth, associated with each bit fieldof the channel bitmap. Configuration of the extensions to the channelbitmap for supported granularity in EHT environments may be based on theone or more bit indications within a BQR field or EHT operation elementof the control element format 400-a. For example, the bitmap for non-EHTsupported STAs (for example, HE STAs) served by the AP on the BSS wouldmaintain the legacy meaning as defined by IEEE 802.11ax or 802.11beamendments to the 802.11 set of standards. In other examples, the bitmapfor EHT supported STAs served by the AP on the BSS would be based on thesupported EHT functionality, including the determined parameter valuesas indicated by the one or more bit indications.

Additionally or alternatively, the one or more bit indications withinthe BQR field or EHT operation element may indicate permanence orintermittence of the reporting bandwidth and a validity period in thecase of a temporary bandwidth indication. The indication of the validityperiod may specify that the reported bandwidth of the BQR is valid untilthe end of a transmission opportunity (TXOP), TWT service period (SP),or validity period for an enhanced digital channel access (EDCA)parameter for multi-user (MU) contexts. In some examples, the one ormore bit indications within the BQR field or EHT operation element mayindicate signal to noise ratio (SINR) statistics for the BSS andinteraction indications between the BSS of the communication and otherBSSs (OBSSs). The interaction indications may be used for schedulingpurposes (for example, to allocate the STA in a sub-channel that isreported an idle) and interference avoidance (for example, not toallocate or transmit to the STA in a sub-channel reported as busy).Additionally, in some examples, the reported bandwidth may not becontiguous. In such cases, the BQR may apply to a sub-portion of theintermittent reported bandwidth, such as a primary spectrum, whilepreserving the legacy meaning of the field.

The described operating bandwidth and sub-channel allocations describedin the provided examples for BQR operations are not limiting. Rather,extensions to flexibility and support for rules, structures, andsignaling may vary dynamically to support an EHT environment. Theextensions may include supported functionality for reporting bandwidthextensions beyond what is indicated in the current specification (forexample, 160 MHz for HE devices), in accordance with the IEEE 802.11axor 802.11be amendments to the 802.11 set of standards.

The extensions to flexibility and support for rules, structures, andsignaling may include functionality for reporting bandwidth granularityor refinement within a reporting bandwidth smaller than that indicatedin the current specification. Additionally or alternatively, theextensions may include supported functionality for reporting bandwidthextensions using a supported granularity, with multiple BQR reportingindications. In some examples, the STA may support capability fordetermining, based on an identified operating mode of an operatingbandwidth, a value with a parameter of an additional (second) BQRindication. As detailed above, the BQR indication may indicate a firstset of sub-channels of the operating bandwidth available at the STA andthe second BQR indication may indicate a second set of sub-channels ofthe operating bandwidth available at the STA. For example, for an EHTsupported operating bandwidth allocation of 320 MHz, one or more bitfields of a channel bitmap associated with the BQR indication mayrepresent a sub-channel allocation of a first 160 MHz sub-channel of the320 MHz channel. In addition, one or more bit fields of a channel bitmapassociated with the second BQR indication may represent a sub-channelallocation of a second 160 MHz sub-channel of the 320 MHz channel. Thedescribed operating bandwidth and sub-channel allocations described inthe provided example for multiple BQR operations are not limiting, andmay include various sub-channel allocations within reporting bandwidthextensions beyond what is indicated in the current specification (forexample 160 MHz for HE devices), in accordance with the IEEE 802.11ax or802.11be amendments to the 802.11 set of standards.

FIG. 5A shows an example of a control element format 500-a that supportsa 320 MHz operating bandwidth in accordance with aspects of the presentdisclosure. Control element format 500-a may be usable forcommunications between a STA and an AP. For example, the control elementformat 500-a may be implemented by an STA supporting EHT functionality,for extensions to reporting indications associated with one or morecontrol subfield formats of a control field form. The control field formmay vary in subfield values or in subfield formatting based on supportedfunctionality at the STA, known as a control field variant. The controlfield may contain a sequence of one or more control subfields (forexample, as part of an A-Control subfield) in which each controlsubfield contains a control identification (ID) subfield and controlinformation subfield, in accordance with the IEEE 802.11ax or 802.11beamendments to the 802.11 set of standards.

The STA may identify an operating mode for a supported operatingbandwidth. Based on the identified operating mode, the STA may determinea value for one or more parameters of a BQR for transmission to anassociated AP. For example, the STA set the control ID subfield of acontrol subfield within control element format 500-a to a valueindicative of an operating mode (OM) control of the STA. The OM controlindication may be formatted to include one or more subfields, includinga channel width subfield spanning multiple (for example, 2) bits. Thechannel width subfield may indicate the operating bandwidth widthsupported by the STA for both transmission and reception. The 2 bitstructure of the channel width subfield may correspond to a bitmap 500-bthat includes 4 bit combination values (for example, 0, 1, 2, or 3)associated with reporting the operating bandwidth width, as shown inFIG. 5B.

Based on the supported EHT functionality, the STA may support anencoding scheme within the control information subfield, in which theone or more determined parameter values at the STA may indicategranularity associated with the mode of operation. The STA may performthe encoding according to implementation of one or more bit allocationsavailable within subfields of the control information subfield.Specifically, the STA may use a reserved or unused combination ofallocated bits for subfields of the OM control information subfield tosignal an encoding of the channel width subfield based on the supportedfunctionality and operability of the STA. For example, the UL MUdisable, and UL MU data disable subfields of the OM control informationsubfield may have a reserved bit combination value (such as 1,1).

Additionally or alternatively, the STA may repurpose a reserved bitcombination to indicate an encoding of the channel width subfield thatsupports granularity associated with an EHT mode of operation. Forexample, the STA may repurpose the reserved bit combination within theOM control subfield to indicate a different channel bandwidth encodingthat supports bit value indications for 40 MHz, 80 MHz, 160 MHz, and 320MHz or 160+160 MHz channel spectrum. In another example, the STA mayrepurpose the reserved bit combination within the OM control subfield toindicate a different channel bandwidth encoding that supports bit valueindications for any combination of 40 MHz, 80 MHz, 160 MHz, 80+80 MHz,320 MHz, and/or 160+160 MHz channel spectrum.

Due to the channel bandwidth encoding for EHT supported functionalitybeing indicated according to a reserved field value of the OM controlset, non-EHT STAs may continue to support the legacy meaning for channelbandwidth encoding. That is, EHT supported STAs may repurpose availablereserved bits of the OM control subfield to indicate a differentencoding scheme for the channel width subfield. In contrast, non-EHTSTAs may obviate the repurposing mechanism, providing indication thatthe encoding as described within IEEE 802.11ax or 802.11be amendments tothe 802.11 set of standards (for example, four values associated withchannel widths of 20 MHz, 40 MHz, 80 MHz, and 160/80+80 MHz) may bemaintained.

The described channel width allocations and encoding schemes describedin the provided examples for OM control are not limiting. Rather,extensions to flexibility and support for rules, structures, andsignaling may vary dynamically to support an EHT environment. Theextensions may include supported functionality for reporting channelwidths larger than what is indicated in the current specification, inaccordance with the IEEE 802.11ax or 802.11be amendments to the 802.11set of standards. Additionally or alternatively, the extensions mayinclude supported functionality for an encoding scheme associated withchannel width refinements smaller than that indicated in the currentspecification.

FIG. 6 shows an example of a process flow 600 for communications betweenan AP and an STA that supports a 320 MHz operating bandwidth inaccordance with aspects of the present disclosure. Process flow 600 mayinclude one or more STAs 115 and APs 105 managing a BSS of thecommunication environment, as described in FIG. 1. As described, addedflexibility to functionality for reporting mechanisms or subfieldindications may be supported by an AP 105 or an STA 115 of theenvironment, for increased granularity for channel bitmap or operatingbandwidth indication. The extensions to flexibility and supportedfunctionality may be in accordance with EHT capability within theenvironment.

Process flow 600 may illustrate support for extensions to reportingindications associated with one or more control subfield formats of acontrol field form of a control field. The control field form may varyin subfield values or in subfield formatting based on supportedfunctionality at the STA, known as a control field variant. The controlfield may contain a sequence of one or more control subfields (forexample, as part of an A-Control subfield) in which each controlsubfield contains a control ID subfield and control informationsubfield.

At 605, an AP 105-b may transmit a trigger frame to one or more STAs,including an STA 115-b to coordinate uplink transmission. The triggerframe may be formatted to include one or more subfields spanning asequence of bits. The one or more subfields of the trigger frame includeinformation such as a payload length, bandwidth, RU allocation, andmodulation scheme, as well as one or more request indications forreporting by the receiving STA 115-b.

At 610, the STA 115-b may receive and process the trigger frame. Basedon the processing, the STA may determine one or more request indicationsfor reporting and identify an operating mode for an operating bandwidthof the STA 115-b. Based on operability enhancements associated with anidentified operating mode (for example, EHT capability), the STA 115-bmay determine a value for one or more parameters of a BQR. For example,the STA 115-b may support extensions to flexibility for fields, frames,or features of a reporting indication associated with formatting of oneor more control subfields of a control field. In some examples, theformatting may include dynamically altering the sub-channel associationfor each bit within the channel bitmap of a BQR. In other cases, theformatting may include implementation of an encoding scheme foridentifying a channel width, as part of an OM control subfield.

At 615, the STA 115-b may transmit a HE TB PPDU response to the AP105-b, including the subfield value and extensions supported for themode of operation. The extensions may be indicated within the controlfield formatting of the response based on default operations associatedwith the EHT functionality or one or more modes, bit combinations, oractive fields indicating the active mode is supported. Enablement of theextensions may be based on one or more of capability (for example,reported bandwidth) at the AP 105-b or STA 115-b, the operatingbandwidth of the BSS, or a request for reporting information.

At 620, the AP 105-b may receive the HE TB PPDU response transmissionand process the control field of the PPDU, including the extensionindications for supported granularity of EHT operations. Based on theextension indications, the AP 105-a may determine the supportedsub-channel allocations available at the STA 115-b from a BQR indicationor determine the available channel width from an OM control subfieldindication. At 625, the AP 105-b may configure a resource assignment forthe STA 115-b based on the supported extensions to functionality for EHToperations.

FIG. 7A shows an example of a TWT element format 700-a usable forwireless communications between an AP and an STA that supports a 320 MHzoperating bandwidth in accordance with aspects of the presentdisclosure. TWT element format 700-a may be usable for communicationsbetween a STA and an AP. For example, the TWT element format 700-a maybe implemented by an STA supporting EHT functionality, for extensions toreporting indications associated with a TWT element. In some examples,the extensions to a reporting indication may include TWT ParameterInformation associated with an individual TWT negotiation procedure. TheTWT element may contain a sequence of one or more subfields, including aTWT parameter information subfield spanning a variable number of octetsand formatted according to a TWT parameter set field format, inaccordance with the IEEE 802.11ax or 802.11be amendments to the 802.11set of standards.

An STA supporting EHT functionality may be configured for negotiatingscheduling operability with an AP according to a TWT. The TWTfunctionality may define a specific time or set of times for the STA toaccess and communicate on the BSS. The STA may use the TWT functionalityto reduce energy consumption by, for example, entering a sleep stateuntil the one or more configured wake periods arrive. Due totransmission of beacons, management frames, and additional frameindications by the AP, a concentration of signaling on the primaryspectrum (for example, including the primary channel/sub-channel) of theBSS may impede maximization of TWT functionality support at the STA. TheSTA may instead, negotiate enablement of frame exchange on a non-primarysub-channel (for example, a secondary sub-channel) as part of asub-channel selective transmission (SST) procedure.

The STA may identify an operating mode for a supported operatingbandwidth. Based on the identified operating mode, the STA may determinea value for one or more parameters of a TWT element. For example, aspart of the individual TWT negotiation, the STA may format the TWTparameter information subfield to an individual TWT parameter set fieldformat. The individual TWT parameter set field format may include asequence of subfields spanning a sequence of octets. The sequence ofsubfields may include a TWT channel subfield spanning a single octet.The TWT channel subfield may include an available channel bitmapspanning multiple (for example 8) bits, for indication of whichsub-channels of the operating bandwidth are permitted by the STA forenabling frame exchange with the AP.

Based on the supported EHT functionality, the STA may supportflexibility extensions within the available channel bitmap, to indicategranularity associated with the mode of operation. The flexibilityextensions may promote scaling of represented sub-channel features (forexample, bandwidth granularity) associated with the bit field values ofthe channel bitmap. The flexibility extensions may be enabled by the STAbased on default operations associated with the EHT functionality or oneor more mode, bit combinations, or active fields indicating the activemode is supported, including one or more bit indications within a TWTfield or EHT operation elements of the control element format 700-a.

In some examples, the STA may dynamically alter the sub-channelassociation for each bit within the channel bitmap based on theoperating bandwidth associated with an individual TWT negotiationprocedure. In some examples, the STA may dynamically alter thegranularity of the available channel bitmap based on the supportedoperating bandwidth of the BSS. That is, the STA may alter thegranularity of the channel bitmap according to the AP operation of theBSS supporting the communication link. In some examples, the STA maydynamically alter the granularity of the available channel bitmap basedon the supported capability (for example, reported bandwidth) at the STAor based on the supported capability (for example, reported bandwidth)at the AP.

The alterations may be such that each bit field within the channelbitmap 700-b is representative of an equal allocation of the supportedoperating bandwidth, as shown in FIG. 7B. For example, for an EHTsupported operating bandwidth allocation of 320 MHz, each bit field ofthe 8 bit channel bitmap for the control information subfield mayrepresent a sub-channel allocation of 40 MHz. In other examples, for anEHT supported operating bandwidth allocation of 80 MHz, each bit fieldof the 8 bit channel bitmap for the control information subfield mayrepresent a sub-channel allocation of 10 MHz.

Alternatively, as shown in FIG. 7C, the alterations to the sub-channelassociation may be such that each bit field bitmap within the channelbitmap 700-c for the parameter information subfield may correspond to ascaled distribution pattern within the channel bitmap such that each bitfield within the channel bitmap may correspond to sub-channels ofvarious bandwidths. For example, for an EHT-supportedoperating-bandwidth allocation of 320 MHz, one or more bit fields of the8 bit channel bitmap may represent a sub-channel allocation of 20 MHz,one or more alternative bit fields may represent a sub-channelallocation of 60 MHz, 80 MHz, or any other sub-channel allocation withinthe operating bandwidth. In other examples, for an EHT-supportedoperating-bandwidth allocation 80 MHz, one or more bit fields of the 8bit channel bitmap may represent a sub-channel allocation of 10 MHz, oneor more alternative bit fields may represent a sub-channel allocation of20 MHz, 30 MHz, or any other sub-channel allocation within the operatingbandwidth.

Based on the one or more parameters of the TWT parameter informationsubfield, including the supported bit field value indication, the STAtransmits the TWT element to an associated AP. The STA may negotiateenablement of frame exchange availability for performing an SSTprocedure within spectrum associated with at least a portion of thesub-channel partitions (for example, 8 sub-channel partitions) of theoperating bandwidth, associated with each bit field of the channelbitmap. Configuration of the extensions to the channel bitmap forsupported granularity in EHT environments may be based on the one ormore bit indications within a TWT field or EHT operation element of theTWT element format 700-a. The bitmap for non-EHT supported STAs (forexample, HE STAs) served by the AP on the BSS would maintain the legacymeaning as defined by IEEE 802.11ax or 802.11be amendments to the 802.11set of standards.

In some examples, the one or more bit indications within the TWT fieldor EHT operation element may indicate permanence or intermittence of thereporting bandwidth and a validity period in the case of a temporarybandwidth indication. The one or more bit indications may be used forscheduling purposes (for example, to allocate the STA in a sub-channelthat is reported an idle) and interference avoidance (for example, notto allocate or transmit to the STA in a sub-channel reported as busy).Additionally, in some examples, the reported bandwidth may not becontiguous. In such cases, the TWT may apply to a sub-portion of theintermittent reported bandwidth, such as a primary spectrum, whilepreserving the legacy meaning of the field.

The described operating bandwidth and sub-channel allocations describedin the provided examples for individual TWT negotiation are notlimiting. Rather, extensions to flexibility and support for rules,structures, and signaling may vary dynamically to support an EHTenvironment. The extensions may include supported functionality forreporting bandwidth extensions beyond what is indicated in the currentspecification (for example 160 MHz for HE devices), in accordance withthe IEEE 802.11ax or 802.11be amendments to the 802.11 set of standards.

Additionally or alternatively, the extensions to flexibility and supportfor rules, structures, and signaling may include functionality forreporting bandwidth granularity or refinement within a reportingbandwidth, the granularity or refinement being smaller than thatindicated in other signaling applications. Additionally oralternatively, the extensions may include supported functionality forreporting bandwidth extensions using a supported granularity withmultiple BQR reporting indications. In some examples, the STA maysupport capability for determining, based on an identified operatingmode of an operating bandwidth, a value with a parameter of anadditional (second) TWT element, as part of a TWT negotiation. Asdetailed above, the TWT element may indicate a first set of sub-channelsof the operating bandwidth permitted by the STA for enabling frameexchange. In addition, and the second TWT element may indicate a secondset of sub-channels of the operating bandwidth permitted by the STA forenabling frame exchange. For example, for an EHT-supported operatingbandwidth allocation of 320 MHz, one or more bit fields of a channelbitmap may be associated with a TWT channel subfield of the TWT element.In some examples, the channel bitmap may represent a sub-channelallocation of a first 160 MHz. In addition, one or more bit fields of achannel bitmap associated with a TWT channel subfield of the TWT elementmay represent a sub-channel allocation of a second 160 MHz. Thedescribed operating bandwidth and sub-channel allocations described inthe provided example for multiple TWT elements are not limiting, and mayinclude various sub-channel allocations within reporting bandwidthextensions beyond what is indicated in the current specification (forexample 160 MHz for HE devices), in accordance with the IEEE 802.11ax or802.11be amendments to the 802.11 set of standards.

FIG. 8 shows an example of a process flow 800 for communications betweenand AP and an STA that supports a 320 MHz operating bandwidth inaccordance with aspects of the present disclosure. Process flow 800 mayinclude one or more STAs 115 and APs 105 managing a BSS of thecommunication environment, as described in FIG. 1. As described, addedflexibility to supported functionality for reporting mechanisms orsubfield indications may be supported by an AP 105 or an STA 115 of theenvironment, for increased granularity for channel bitmap or operatingbandwidth indication. The extensions to flexibility and supportedfunctionality may be in accordance with EHT capability within theenvironment.

Process flow 800 may illustrate supported extensions to reportingindication associated with extensions to reporting indication associatedwith a TWT element, such as TWT Parameter Information associated with anindividual TWT negotiation procedure. The TWT element may contain asequence of one or more subfields, including a TWT parameter informationsubfield spanning a variable number of octets and formatted according toa TWT parameter set field format.

At 805, an STA 115-c implements an SST operation as part of a TWTnegotiation procedure. The STA 115-c may identify an operating mode foran operating bandwidth of the STA 115-c. The STA 115-c may determine avalue for one or more parameters of the TWT element. For example, theSTA 115-c may set a capabilities element of the TWT element format to avalue indicative of SST support and initiate individual TWT negotiationwith an AP 105-c of a BSS. The STA 115-c may transmit a request for asecondary channel that is permitted for RU allocation. The TWT requestmay contain a TWT channel field indicating a secondary channel requestedby the STA 115-c.

At 810, the AP 105-c may receive the TWT request as part of the TWTnegotiation procedure. The AP 105-c may process the request, includingthe SST support indication for performing frame exchange on a secondarychannel of the BSS. The AP 105-c may then allocate an RU in a secondarychannel specified in the TWT channel field of the TWT request.

At 815, The AP 105-c may set a bit in a TWT channel field of a TWTresponse indicating a secondary channel that is permitted for RUallocation as part of a TWT operating procedure at the STA 115-c. AP105-c may then transmit the TWT response to the STA 115-c.

FIG. 9 shows an example of a common information field format 900 usablefor wireless communications between an AP and an STA that supports a 320MHz operating bandwidth in accordance with aspects of the presentdisclosure. For example, the AP may transmit a trigger frame to allocateresources for one or more HE TB PPDUs, which in some examples maycoordinate uplink transmissions by the STA. The trigger frame mayinclude a payload length, bandwidth, RU allocation, and modulationscheme information for the responding STA. The trigger frame may beformatted to include a sequence of one or more subfields, which may beincluded in a MAC header. The sequence of one or more subfields mayinclude a common information field, spanning 8 or more octets, and auser information field, spanning 5 or more octets. Formatting of thecommon information field may be in accordance with the IEEE 802.11ax or802.11be amendments to the 802.11 set of standards.

The common information field may be formatted to include one or moresubfields, including an UL BW subfield spanning 2 bits. The UL BWsubfield may indicate the bandwidth in the HE-SIG-A field of the HE TBPPDU. The 2-bit structure of the UL BW subfield may correspond to 4 bitcombination values (for example, 0, 1, 2, or 3) associated withreporting the operating bandwidth for uplink signaling.

Based on the supported EHT functionality at the responding STA, the APmay extend an encoding scheme or resource allocation structure withinthe one or more subfields of the common information field to indicategranularity associated with the mode of operation at the STA. The AP mayenable a different encoding scheme within the UL BW subfield of thecommon information field, to support operable granularity at thereceiving STA of the trigger frame based on the active mode (forexample, EHT functionality). In some examples, the AP may use a reservedor unused combination of allocated bits for subfields of the commoninformation field (for example, bits in the trigger dependent commoninformation field) to signal an encoding of the UL BW subfield based onthe supported functionality and EHT operability of the STA. By signalingthe encoding within the common information field, the encoding schememay apply to the entire trigger frame. The STA may repurpose thereserved bit combination to indicate an encoding of the channel widthsubfield that supports granularity associated with an EHT mode ofoperation. For example, the AP may repurpose the reserved bitcombination available in the common information field to indicate adifferent channel bandwidth encoding that supports bit value indicationsfor 40 MHz, 80 MHz, 160 MHz, and 320 MHz or 160+160 MHz channelspectrum. In another example, the AP may repurpose the reserved bitcombination available in the common information field to indicate adifferent channel bandwidth encoding that supports bit value indicationsfor any combination of 40 MHz, 80 MHz, 160 MHz, 80+80 MHz, 320 MHz,and/or 160+160 MHz channel spectrum.

Due to the channel bandwidth encoding for EHT supported functionalitybeing indicated according to a reserved bit combination in the commoninformation field, non-EHT STAs may continue to support the legacymeaning for channel bandwidth encoding. That is, the AP may repurposeavailable reserved bits of the common information field to indicate adifferent encoding scheme for the UL BW subfield according to EHT STAs.In contrast, non-EHT STAs may obviate the repurposing mechanism,providing indication that the encoding as described within IEEE 802.11axor 802.11be amendments to the 802.11 set of standards (for example, fourvalues associated with channel widths of 20 MHz, 40 MHz, 60 MHz, and160/80+80 MHz) may be maintained.

The encoding scheme described in the provided examples for the UL BWsubfield is not limiting. Rather, extensions to flexibility and supportfor rules, structures, and signaling may vary dynamically to support anEHT environment. The extensions may include supported functionality forreporting channel widths larger than what is indicated in the currentspecification, in accordance with the IEEE 802.11ax or 802.11beamendments to the 802.11 set of standards. Additionally oralternatively, the extensions may include supported functionality for anencoding scheme associated with channel width refinements smaller thanthat indicated in the current specification.

FIG. 10 shows an example of a user information field format 1000 usablefor wireless communications between an AP and an STA that supports a 320MHz operating bandwidth in accordance with aspects of the presentdisclosure. The user information field format may be usable forcommunications between a STA and an AP. For example, the AP mayconfigure a trigger frame to allocate resources for, and solicit, one ormore HE TB PPDUs indicating coordination for uplink transmission by theSTA. The trigger frame may include a payload length, bandwidth, RUallocation, and modulation scheme information for the responding STA.The trigger frame may be formatted to include a sequence of one or moresubfields, referred to as the MAC header. The sequence of one or moresubfields may include a common information field, spanning 8 or moreoctets, and a user information field, spanning 5 or more octets.Formatting of the common information field may be in accordance with theIEEE 802.11ax or 802.11be amendments to the 802.11 set of standards.

The user information field may be formatted to include one or moresubfields, including an RU allocation subfield. The RU allocationsubfield may include an available channel bitmap, spanning 8 bits,encoded for indication of the RU of the HE TB PPDU for the receivingSTA. Based on the supported EHT functionality at the receiving STA, thebitmapping may be encoded to indicate granularity associated with themode of operation. Specifically, the AP may enable an encoding schemewithin the RU allocation subfield such that one or more bit values ofthe bitmapping, denoted as reserved values by legacy devices, maysupport resource extension for operating bandwidth associated with EHTfunctionality.

In some examples, the AP may use a reserved or unused combination ofallocated bits for subfields of the user information field (for example,bits in the trigger dependent user information field) to signalextensions to the encoding scheme of the RU allocation subfield based onthe supported functionality and EHT operability of the STA. By signalingthe encoding within the user information field, the encoding scheme maybe directed to the recipient STA. The AP may enable encoding of thebitmapping for the RU allocation subfield to signal granular extensionsassociated with an EHT mode of operation. For example, the AP mayrepurpose the range of bit combinations denoted as reserved (for example69-127) of the RU allocation subfield to indicate support for RUallocations in 320 MHz or 160+160 MHz.

Due to the encoding scheme for RU allocation based on EHT-supportedfunctionality being indicated according to a reserved bit combination inthe user information field, non-EHT STAs may continue to support thelegacy meaning for bit combinations of the RU allocation subfield. Thatis, the AP may repurpose the reserved combination of bits to indicate adifferent encoding scheme for the UL BW subfield within reserved bits ofthe user information field according to EHT STAs. In contrast, non-EHTSTAs may obviate the repurposing mechanism, providing indication thatthe encoding as described within IEEE 802.11ax or 802.11be amendments tothe 802.11 set of standards (for example, bit combinations 69-127 of thebitmapping may be denoted as reserved) may be maintained.

The encoding scheme described in the provided examples for the RUallocation subfield is not limiting. Rather, extensions to flexibilityand support for rules, structure, and signaling may dynamically vary tosupport an EHT environment. The extensions may include supportedfunctionality for reporting channel widths larger than what is indicatedin the current specification, in accordance with the IEEE 802.11ax or802.11be amendments to the 802.11 set of standards. Additionally oralternatively, the extensions may include supported functionality for anencoding scheme associated with channel width refinements smaller thanthat indicated in the current specification.

FIG. 11 shows an example of a process flow 1100 for communicationsbetween an AP and an STA that supports a 320 MHz operating bandwidth inaccordance with aspects of the present disclosure. Process flow 1100 mayinclude one or more STAs 115 and APs 105 managing a BSS of thecommunication environment, as described in FIG. 1. As described, addedflexibility to supported functionality for reporting mechanisms orsubfield indications may be supported by an AP 105 or an STA 115 of theenvironment, for increased granularity for channel bitmap or operatingbandwidth indication. The extensions to flexibility and supportedfunctionality may be in accordance with EHT capability within theenvironment.

Process flow 1100 may support extensions to reporting indicationsassociated with one or more field formats of a trigger frame. Thetrigger frame may contain a sequence of one or more fields spanning asequence of bits. The one or more subfields of the trigger frame includeinformation such as a payload length, bandwidth, RU allocation, andmodulation scheme, as well as one or more request indications forreporting.

At 1105, an AP 105-d may configure a trigger frame format for STAs,including the STA 115-d, associated with a BSS it manages. The triggerframe may be formatted to include a sequence of one or more fields in aMAC header. The sequence of one or more fields may include a commoninformation field and a user information field. Additionally oralternatively, the common information field may be formatted to includea sequence of subfields, including an UL BW subfield. The userinformation field may also be formatted to include a sequence ofsubfields, including an RU allocation subfield. Based on the supportedEHT functionality at the responding STAs, including the STA 115-d, theAP 105-d may extend an encoding scheme or resource allocation structurewithin the one or more subfields of the common information subfield orthe user information subfield, to indicate granularity associated withthe mode of operation at the STA 115-d.

At 1110, the AP 105-d may transmit the trigger frame to one or morerecipient STAs 115, including the STA 115-d, to coordinate uplinktransmission. The trigger frame may be formatted to include one or morereserved bit indications for enabling an encoding scheme associated withgranularity of the active mode for EHT supported STAs 115.

At 1115, the STA 115-d may receive and process the trigger frame. Basedon the processing, the STA 115-d may determine an encoding scheme forreporting a supported operating bandwidth associated with EHT operation.The STA 115-d may support extensions for flexibility for fields, frames,or features of a reporting mechanism. In some examples, supportedextensions may include an encoding of the UL BW subfield within thecommon information field with granularity to support EHT operation. Inother cases, supported extensions may include an encoding of the RUallocation subfield within the user information field with granularityto indicate operations associated with operating bandwidth for EHTfunctionality.

FIG. 12 shows an example of a schematic diagram 1200 between an AP andan STA that supports a 320 MHz operating bandwidth in accordance withaspects of the present disclosure. An AP 105-e may manage a BSSassociated with resource allocation and communication for one or moreSTAs 115. Each of the STAs 115 may be served on one or more sub-channelallocations of the BSS and support respective operating bandwidthsaccording to an operating mode. The one or more STAs 115 may beperceived as neighboring STAs relative to each STA 115.

Each of the STAs 115 may support a carrier sensing mechanism to avoidcollisions associated with multiple data transmissions by STAs on commonresources over a duration. For example, an STA (such as the STA 115-e orthe STA 115-f) may identify data for transmission to the AP 105-e andsense the medium for the one or more sub-channel allocations of the BSS.The supported carrier sensing mechanism may use collision avoidancetechniques implementing request-to-send (RTS) and clear-to-send (CTS)messaging between AP 105-e and the STAs 115 and in which peer STAs 115relative to the RTS/CTS implementation may extract values from the RTSand CTS messages for updating configured NAVs.

As a condition for accessing the medium, an STA 115 may monitor (checkthe value of) a configured NAV, which is a counter resident at the STA115 that is representative of the amount of time that remains on theshared channel that has been reserved by other STAs. For example, an STA115-f may observe the RTS/CTS exchange between the AP 105-e and an STA115-d,e and based on the exchange, update a NAV value associated withallocated resources (for example, assigned RUs) of the operatingbandwidth. Prior to attempting to perform frame transmission, the STA115-f may perform a NAV monitoring 1205 associated with the operatingbandwidth and, in the case of present data traffic associated with theSTA 115-e, abstain from data signaling until after the counterassociated with the configured NAV has expired.

Based on the supported EHT functionality, as described above, the STA115-f may support flexibility extensions to performing the NAV checkassociated with the operating bandwidth. In some cases, the STA 115-fmay perform a NAV checking procedure for one or more sub-channels inaddition to, or as an alternative to, the primary channel associatedwith the operating bandwidth. By performing a NAV check on non-primarysub-channels, the STA 115-f may support a more granular carrier sensingindication, particularly when the STA 115-f may occupy a set ofsub-channels distant to the primary channel of the operating bandwidth.For example, the STA 115-f may operate in an extended bandwidth (forexample, 320 MHz) associated with supported EHT functionality. The STA115-f may be allocated resources on the upper 60 MHz of the operatingbandwidth, while the primary channel may span a lower 20 MHz of theoperating bandwidth.

Due to the spectral disparity between sub-channels occupied by the STA115-f and the primary channel of the operating bandwidth, the STA 115-fmay implement a granular NAV check 1205 local to the occupiedsub-channels. Such an implementation may be referred to as a per-channelNAV check. In some cases, the per-channel NAV check 1205 may include acarrier sensing mechanism for each 20 MHz allocation of the operatingbandwidth (for example, for a 320 MHz bandwidth, 16 NAV checks would besupported for each 20 MHz allocation). In other cases, the per-channelNAV check 1205 may include carrier sensing for one or more sets ofsub-channels (for example, 80 MHz or 120 MHz channels) within theoperating bandwidth.

Additionally or alternatively, the system corresponding to the EHTenvironment may be configured to include additional flexibility andsupport extensions based on the extended operating bandwidth. In somecases, one or more sub-channel allocations of the operating bandwidthmay support an associated primary channel. For example, for a 320 MHzoperating bandwidth, the system may be configured to support a firstprimary channel associated with the upper 160 MHz of the bandwidth and asecond primary channel associated with the lower 160 MHz of thebandwidth. The one or more primary channels may support beacons whichsupport duplication of management frame formats. In addition, the one ormore primary channels may be configured with flexibility extensionsassociated with concurrent operations on traditional Wi-Fi frequencybands (for example, such as the 5 GHz band, the 2.4 GHz band, the 60 GHzband, the 3.6 GHz band, the 900 MHz band) and 6 GHz bandwidth spectrum,spanned by the operating bandwidth for EHT functionality. Each of theSTAs 115 may observe the primary channels of the concurrent operationsbased in part on the supported functionality at the operating frequencyband of the STA. For example, the STA 115-f may support operation and 5GHz bandwidth spectrum. Based on the supported operation, the STA 115-fmay observe the primary channel associated with the 5 GHz bandwidthspectrum. In other examples, the STA 115-f may support operation and 6GHz bandwidth spectrum. Based on the supported operation, the STA 115-fmay observe the primary channel associated with the 6 GHz bandwidthspectrum. Additionally or alternatively, in other examples, the STA115-f may support extended capability (for example, compatible withconcurrent operation) within the extended bandwidth may observe both theprimary channel within the 5 GHz band and the 6 GHz band.

It should be understood that the described operating bandwidth andsub-channel allocations described in the provided examples forper-channel NAV operations are not limiting. Rather, extensions toflexibility and support for rules, structures, and signaling may varydynamically to support an EHT environment. The extensions may includesupported functionality for reporting bandwidth extensions beyond whatis indicated in the current specification (for example 160 MHz for HEdevices), in accordance with the IEEE 802.11ax or 802.11be amendments tothe 802.11 set of standards. Additionally or alternatively, theextensions may include supported functionality for reporting bandwidthgranularity or refinement within a reporting bandwidth smaller than thatindicated in the current specification.

FIG. 13 shows an example of a process flow 1300 for communicationsbetween an AP and an STA that supports a 320 MHz operating bandwidth inaccordance with aspects of the present disclosure. Process flow 1300 mayinclude one or more STAs 115 and APs 105 managing a BSS of thecommunication environment, as described with reference to FIG. 1. Asdescribed, added flexibility to supported functionality for carriersensing mechanisms may be supported by an STA 115 of the environment,for increased granularity. The extensions to flexibility and supportedfunctionality may be in accordance with EHT capability within theenvironment.

Process flow 1300 may illustrate support extensions for localized (forexample, per-channel) NAV checking as part of medium sensing operationassociated with allocated resources of an operating bandwidth. Theoperating bandwidth may be configured to include more than one primarychannel based on supported flexibility extensions. For example, one ormore sub-channel allocations of the operating bandwidth may support anassociated primary channel. The one or more primary channels may supportbeacons that support duplication of management frame formats. Inaddition, the one or more primary channels may be configured withflexibility extensions associated with concurrent operations ontraditional Wi-Fi frequency bands (for example, such as the 5 GHz band,the 2.4 GHz band, the 60 GHz band, the 3.6 GHz band, the 900 MHz band)and 6 GHz bandwidth spectrum, spanned by the operating bandwidth for EHTfunctionality.

At 1305, an STA 115-g may identify potential data for transmission tothe access point 105-f, in which the access point 105-f supportscommunication on resources (such as one or more sub-channels) of anoperating bandwidth. For example, the operating bandwidth may includeone or more primary channels spanning spectrum included on traditionalWi-Fi frequency bands (for example, such as the 5 GHz band, the 2.4 GHzband, the 60 GHz band, the 3.6 GHz band, the 900 MHz band) or 6 GHzbandwidth spectrum.

At 1310, STA 115-g may monitor one or more NAVs associated with the oneor more sub-channels of the allocated resources. The NAV monitoring maybe performed by STA 115-g according to a bit value indication includedin a carrier sense bit. In some cases, the NAV monitoring may include acarrier sensing mechanism for each 20 MHz allocation of the operatingbandwidth (for example, for a 320 MHz bandwidth, 16 NAV monitoring(checks) would be supported for each 20 MHz allocation). In other cases,the NAV monitoring may include carrier sensing for one or more sets ofsub-channels (for example, 80 MHz or 40 MHz channels) within theoperating bandwidth. Based on the NAV monitoring, the STA 115-g maymaintain a timer (or a “counter”) for each of the one or more NAVsassociated with the NAV monitoring. For example, for 320 MHz bandwidthwith 16 NAVs supporting each 20 MHz allocation, the STA 115-g maymaintain 16 separate timers.

At 1315, STA 115-g may sense the medium for at least one sub-channel ofthe allocated resources based on determining that one or more NAVsassociated with one or more sub-channels are inactive. The one or moreinactive NAVs may indicate that the associated spectrum is not occupiedby data traffic from neighboring STAs 115, and that frame transmissionmay be initiated.

FIG. 14 shows an example of a schematic diagram 1400 that supportsextensions for operating a large bandwidth BSS in accordance withaspects of the present disclosure. An AP 105-g may manage a BSSassociated with resource allocation and communication for one or moreSTAs 115. Each of the STAs 115 may be served on one or more sub-channelallocations of the BSS and may be perceived as neighboring STAs relativeto each STA 115.

An AP 105-g may signal one or more NDP frames (known as null packets)1405 to STAs 115 on the managed BSS, including STA 115-h. The one ormore null packets 1405 may span a wide bandwidth in accordance with theextended operating bandwidth. STA may process the null packets 1405 anddetermine a received signal strength associated with the transmission.The determination by the STA 115-h may be based on one or morecharacteristics associated with the received signal, includingcalculated signal-to-noise ratio (SNR) values. Based on thedetermination, STA 115-h may provide an uplink CQI indicationcorresponding to the transmitted null packets 1405. In some cases, theSTA 115-h may be configured for EHT functionality and supportenhancements to CQI reporting fields. STA 115-h may format a CQI report1410 within a compressed beamforming and CQI report field. Thecompressed beamforming and CQI report field may be included within acompressed beamforming action frame 1401, spanning a sequence of octets.The size of the CQI report 1410 may be dependent on values indicated inthe MIMO control field of the action frame.

Due to the extended operating bandwidth supported by EHT functionality,STA 115-h may provide unsolicited CQI report signaling to AP 105-g. Theunsolicited CQI reporting may be provided in supplement with solicitedCQI requested by AP 105-g. The unsolicited CQI reporting may aid the AP105-g in efficiently scheduling STA 115-h within the enhanced bandwidthof the BSS. STA 115-h may enable indication for the unsolicited CQIreport via a bit in an EHT OP element or by repurposing a reserved fieldof the action frame (for example, a reserved field in the MIMO controlfield). Alternatively, AP 105-g may indicate support for receiving anunsolicited CQI report via a bit indication formatted within an EHTcapabilities element.

Further, based on the supported EHT functionality, STA 115-h may supportenhanced granularity flexibility for CQI reporting associated withassigned resource units (RUs). Specifically, STA 115-h may enable agranular flexibility associated with tone resource allocations tosupport flexibility enhancements on the operating bandwidth. Forexample, in contrast to the current specification within the 802.11 setof standards, where CQI granularity is fixed to 26-tone RUs, STA 115-hmay support an allocation granularity based on the overall operatingbandwidth. For example, in some cases, STA 115-h may support a CQIreport spanning a resource allocation spanning a larger tone granularity(for example, 52 tone, 106 tone, etc.) based on extended operatingbandwidth. In other examples, STA 115-h may support a CQI reportspanning a resource allocation spanning a smaller tone granularity dueto refined resource assignment for the STA.

It should be understood that the described operating bandwidth andsub-channel allocations described in the provided examples for CQIreport signaling are not limiting. Rather, extensions to flexibility andsupport for rules, structure, and signaling may be dynamically variantto support an EHT environment. The extensions may include supportedfunctionality for reporting bandwidth extensions beyond what isindicated in the current specification (for example 160 MHz for HEdevices), in accordance with the IEEE 802.11ax or 802.11be amendments tothe 802.11 set of standards. Further, the extensions may includesupported functionality for reporting bandwidth granularity orrefinement within a reporting bandwidth smaller than that indicated inthe current specification.

FIG. 15 shows an example of a process flow 1500 that supports extensionsfor operating a large bandwidth BSS in accordance with aspects of thepresent disclosure. Process flow 1500 may include one or more STAs andAPs managing a BSS of the communication environment, as described withreference to FIG. 1. As described, added flexibility to CQI reportingmay be supported by an STA of the environment, for enhanced granularity.The extensions to flexibility and supported functionality may be inaccordance with EHT capability within the environment.

Process flow 1500 may illustrate support extensions for flexiblegranularity associated with CQI reporting for allocated resources of anoperating bandwidth. A CQI report may be included in a compressedbeamforming and CQI report field for a compressed beamforming actionframe. The size of the CQI report field may be dependent on valuesindicated in the MIMO control field of the action frame.

At 1505, an STA 115-i may process null packets received from AP 105-hand determine a CQI indication for sub-channels of the operatingbandwidth. STA 115-i may determine a granularity of the CQI indicationbased on one or more of the operating bandwidth of STA 115-i, abandwidth in a solicitation for the CQI, an operating bandwidth of AP105-h, or a bandwidth of a response that includes the CQI report (forexample, bandwidth of compressed beamforming action frame). Granularityof the CQI indication of the CQI report may be based on the overallbandwidth (for example, higher bandwidth including higher granularity,lower bandwidth including lower granularity).

AT 1510, STA 115-i may transmit the CQI report to AP 105-h as a reportfield of the action frame. In some cases, STA 115-i may transmit the CQIreport based on a solicited CQI request indication provided by AP 105-h.In other cases, STA 115-i may transmit the CQI report unsolicited. Anunsolicited mode for providing CQI indication at STA 115-i may beenabled via bit of an EHT OP element or by repurposing a field of theaction frame (for example, a reserved field of the MIMO Control field).Alternatively, an unsolicited mode for providing CQI indication at STA115-i may be enabled by indicated support for receiving unsolicited CQIat AP 105-h via a bit in an EHT capabilities element.

The device 1605 may be anexample of aspects of a STA as described herein. The device 1605 mayinclude a receiver 1610, a communications manager 1615, and atransmitter 1620. The device 1605 may also include a processor. Each ofthese components may be in communication with one another (for example,via one or more buses).

Information may be passed on toother components of the device. The receiver 1610 may be an example ofaspects of the transceiver 1920 described in FIG. 19. The receiver 1610may utilize a single antenna or a set of antennas.

The communications manager 1615 may identify an operating mode for anoperating bandwidth of the station, determine, based on the identifiedoperating mode, a value for a parameter of a bandwidth query report(BQR) or a target wake time (TWT) element, and transmit the BQR or theTWT element including an indication of the determined value for theparameter. The communications manager 1415 may also receive a controltransmission from an access point, identify an operating bandwidth ofthe station, and determine one or more of a channel width, or an uplinkbandwidth, or a resource unit allocation, for the station indicated bythe received control transmission based on the identified operatingbandwidth of the station. The communications manager 1615 may be anexample of aspects of the communications manager 1715 described herein.

The communications manager 1615, or its sub-components, may beimplemented in hardware or code (for example, software or firmware)executed by a processor. If implemented in code executed by a processor,the functions of the communications manager 1615, or its sub-componentsmay be executed by one or more of a general-purpose processor, a DSP, anapplication-specific integrated circuit (ASIC), a FPGA or otherprogrammable logic device, discrete gate or transistor logic, discretehardware components designed to perform the functions described in thepresent disclosure.

The communications manager 1615, or its sub-components, may bephysically located at different locations, including being distributedsuch that portions of functions are implemented at different physicallocations by one or more physical components. In some examples, thecommunications manager 1615, or its sub-components, may be a separateand distinct component in accordance with various aspects of the presentdisclosure.
